The aim of this study was to evaluate the effectiveness of a fixed Twin-block appliance by using a study with a prospective cohort design. Thirty-two children were included in the study over a 2-year period. Cephalometric data were analyzed with the Pancherz cephalometric analysis. Study models were analyzed with the PAR index, and the treatment processes were recorded from the patients' record...

Materials and methods: A 10-year-old male patient, in the mixed dentition stage, presented with anterior crossbite, Class I skeletal base with an ANB angle of 1 degree, retroclined maxillary incisors and an anterior mandibular slide from the point of initial contact to maximum intercuspation. A modified quad helix appliance, made of 0.036" Blue Elgiloy with anterior extension arms, was fabricat...

Premature loss of a primary tooth is one of the most common etiology for malocclusion. Space maintainers are employed to prevent this complication. In anterior region, esthetics is an important concern along with function and space management. Fiber-reinforced composite (FRC) retained space maintainer solves all these purposes ef ficiently and ef fectively. In addition, the technique is simple ...

Single-phase treatment started during late mixed dentition using functional followed by fixed appliance therapy has proven to be the most effective approach to achieve correction of Class II malocclusion. This case report demonstrates the use of this treatment approach in an 11-year-old girl with skeletal and dental Class II malocclusion, large overjet, deep overbite, increased incisor exposure...

AIM The main objective of any orthodontic treatment is to achieve well-established stable occlusal relationship with a definite positive change in facial profile. The purpose of this study was to determine, if such a goal is achievable for patients who could be classified as borderline surgical cases without the invasive use of the actual surgery or, with the use of the recently developed and r...

This clinical report describes a 3.5-year-old boy suffering from chronic daytime fatigue, accumulated snoring and dramatically appearing apnea during sleep. Oxycardiorespirography revealed a breathing pattern similar to repetitive obstructive apnea and an oxygen saturation periodically dropping to 80%. During tidal breathing, fiberoptic bronchoscopy showed aspiration of the aryepiglottic folds ...

Previous studies have indicated that an injured condyle during adolescence is a causative factor for reduced mandibular growth and resulting asymmetry of the mandible. The aim of this study was to examine the nature of mandibular growth after unilateral condylectomy and to elucidate the effects of mandibular advancement. Sixty growing mice were subjected to unilateral condylectomy, and then one...

The effect on isometric strength of the shoulders and limbs while biting in habitual occlusion, on a bite-elevating appliance and on a placebo appliance was analyzed. Twenty female volunteer patients, presenting with temporomandibular pain dysfunction syndrome and obvious loss of vertical dimension, served as subjects. All were weaker to the manual application of the isometric Deltoid Press (ID...

This article describes one variation in Herbst appliance design--the acrylic splint Herbst. Topics discussed include early fixed appliance treatment before Herbst therapy, impression taking, bite registration, and evaluation of appliance fabrication. The specifics of appliance delivery, including bonding of the maxillary appliance when indicated, are also discussed as are the techniques of appl...
